Lethargy kill the daily routine...couple of stretching do wonders but people are not aware of the benefits.. here i see people are too occupied with their daily office and sometime time spent in commuting takes a toll in mind body which gets frustrating. So thinking doing anything extra is putting burden on them.
I reckon the people tired from work and travel, are the ones who should go to the gym or something the most. There is a difference between mentally tired, and physically tired.
